Google Ads for solar installers in San Diego changed the day NEM 3.0 kicked in. The easy "go solar, kill your SDG&E bill" pitch stopped working the way it used to, national lead-gen companies flooded the auction, and half the installers in the county quietly stopped advertising. If you're still here, that's actually good news, because the ones who figured out the new pitch have less competition than they did in 2022.
The pitch has to change first, then the ads
Under NEM 3.0, export credits dropped hard, so solar-only on a small roof in a Mira Mesa tract home doesn't pencil like it did. What does pencil is solar plus storage, especially for anyone with a big evening load: pool pumps, EV chargers, AC in inland heat. SDG&E rates are among the highest in the country, and people know it. Your ads should lead with the bill, the battery, and blackout resilience, not with panels.
That means keywords like "solar battery installer," "Powerwall installer San Diego," "solar and battery cost," and "SDG&E bill too high" often outperform plain "solar panels San Diego," which is now a $30 to $80 click contested by SunPower dealers, Sunrun, and a dozen aggregators reselling your own leads back to you.
Where solar still converts in the county
- Inland heat: Poway, Rancho Bernardo, Escondido, San Marcos, Santee, El Cajon, Lakeside. Bigger roofs, bigger AC bills, more pools. This is the core.
- Affluent coastal and north: Carmel Valley, Rancho Santa Fe, Encinitas, La Jolla. Less bill pressure, more EV and "resilience" motivation. Storage and premium equipment sell here.
- ADU and remodel: New construction triggers Title 24 solar requirements. Contractors building ADUs in City Heights, Chula Vista and Oceanside need an installer; those B2B searches are cheap.
- Military households: Around Camp Pendleton, Tierrasanta and Murphy Canyon there's a lot of turnover with PCS season. Solar is a hard sell to someone leaving in 18 months, so exclude or bid low on those ZIPs.
Targeting: get specific or get robbed
A county-wide radius is how you end up paying for renters in Pacific Beach clicking on "solar." Better:
- Target ZIPs with high owner-occupancy and single-family homes: 92064, 92128, 92127, 92026, 92029, 92078, 92071, 92040, 92019, 92130, 92024, 92067.
- Layer in household income and homeowner status where Google lets you.
- Add a strong negative list: "jobs," "salary," "careers," "free solar," "government program," "lease," "Tesla stock," and the names of every big national brand unless you're a dealer.
- Run a separate small campaign for commercial: warehouses in Otay Mesa, ag buildings in Valley Center, biotech campuses in Sorrento Valley. Different keywords, different landing page.
Landing pages that hold up to a skeptical San Diego homeowner
People here have been door-knocked to death. The landing page needs to do three things: show a real installed-cost range for solar plus a battery, explain NEM 3.0 in two plain sentences, and show your C-10 or C-46 license and local installs with addresses like "Scripps Ranch" and "Chula Vista," not a stock photo of a roof in Arizona. A short form (name, address, average bill) beats a long one. Add call tracking; a surprising share of inland leads still phone.
Budget and management: what's fair
Solar is a high-ticket, long-sales-cycle business, so the numbers are bigger. Expect $40 to $80 per click on core terms and $15 to $35 on battery-specific and long-tail terms. Cost per qualified lead typically lands between $150 and $500, and it can take four to eight weeks from click to signed contract. A serious campaign needs $5,000 to $15,000 a month in media to produce a steady flow; under $3,000 you'll spend most of it learning.
Management fees in solar have a bad history: agencies charging 15 to 20 percent of a $15,000 budget while also reselling leads to your competitors. A flat monthly fee with full account ownership, your own Google Ads account and your own data, is the only fair setup. That's how Arbor runs your ads: you own the account, we run it, and the website is part of the same plan so the landing page doesn't become a separate argument.
Seasonality worth planning around
Search interest climbs when the first big summer SDG&E bills land in July and August, and again after any wildfire-related Public Safety Power Shutoff in the fall. Spring is quieter but cheaper. Budget heavier from June through October and use the slow months to refine.
